Are we allowed to redistribute the new firmware, otherwise we probably need to use dvb_get_firmware.pl ?
Would be nice to know if the new firmware works with the old stick, I can take it upon me to
write a patch for the perlscript that extract the firmware, but I´d like to know if there is need for two different firmwares
or not. The work is already done if we are allowed to redistribute the firmware.....
Stewart I´ve been looking at your C patch and It´s _atleast_ a 2 weeks of learning ahead of me, so I probably can´t contribute anything meaningful, but I´ll start to relearn a bit C anyway so I´ll gladly accept any further version of the code.
TIA

I've attached the C code i wrote to do it, as well as the output from it
(and a non-working, no-longer-applying patch that gets a little bit
closer).

hrrm... now I'm a bit hazy on the details.. but i think that my fw.c
does actually make the firmware loader do that.

Mine did that a bit IIRC.

that i don't know - i just have a new card.

there's existing drivers for the frontend... so it's just gluing them
together... which i've had a bit of a go at, but didn't finish (or get
working).
